Tennessee Zoning 101: What Unzoned Counties Mean for Landowners

8 min readLandWise Team

Roughly half of Tennessee's 95 counties have no county-wide zoning in their unincorporated areas. That isn't a regulatory oversight; it's a deliberate choice the Tennessee General Assembly hands to each county under TCA Title 13, Chapter 7. The county next to yours may have a 200-page zoning code with overlay districts, while yours has nothing on the books at all.

For land buyers, this creates both opportunity and risk. Bledsoe County, for example, has parcel data through the state MAARS system but no county-wide zoning, and an investor in Pikeville is operating under a different rulebook than one in Chattanooga. Knowing which side of that line your parcel sits on is the first piece of due diligence.

How Zoning Works in Tennessee

In Tennessee, zoning authority is not imposed from the state level. Instead, the Tennessee General Assembly grants counties and municipalities the power to adopt zoning regulations through enabling legislation found in Tennessee Code Annotated Title 13, Chapter 7. Under TCA § 13-7-101 through § 13-7-119, counties may establish zoning districts, create planning commissions, and regulate land use, but they are not required to do so.

This means that each of Tennessee's 95 counties decides independently whether to adopt zoning ordinances. Incorporated cities and towns have their own separate zoning authority under TCA § 13-7-201 and can regulate land use within their municipal boundaries regardless of what the surrounding county does.

The result is a patchwork. Metropolitan counties like Davidson (Nashville), Knox (Knoxville), and Hamilton (Chattanooga) have well-established zoning codes with detailed district maps, permitted uses, and development standards. But many of Tennessee's smaller rural counties have never adopted county-wide zoning. Roughly half of Tennessee's 95 counties operate without formal zoning regulations in their unincorporated areas.

What "No Zoning" Actually Means

When a Tennessee county has no zoning, it means the county has not adopted ordinances that divide land into districts with designated permitted uses. In practical terms, this means there are no county-level rules dictating whether a given parcel can be used for residential, commercial, agricultural, or industrial purposes. Your neighbor could theoretically open an auto salvage yard next to your home, and the county would have no zoning ordinance to prevent it.

However, "no zoning" does not mean "no rules." Several layers of regulation can still apply even in unzoned counties:

  • Subdivision regulations. Many counties without zoning still have subdivision regulations adopted by a regional planning commission. These rules govern how land can be divided, requiring minimum lot sizes, road frontage, and recorded plats before new lots can be sold. Before you plan to subdivide a large tract, check with the county planning commission.

  • Deed restrictions and covenants. Private restrictive covenants recorded against a property or subdivision run with the land regardless of county zoning status. These can restrict everything from building materials to livestock. Always review the deed and any recorded covenants before purchasing.

  • State environmental regulations. The Tennessee Department of Environment and Conservation (TDEC) regulates septic systems statewide. Even in counties with no building codes, you will need a septic permit from TDEC before installing a system. Electrical work connected to the grid also requires permits through the state.

  • Floodplain regulations. If a county participates in the National Flood Insurance Program (NFIP), it must enforce minimum floodplain development standards regardless of whether it has zoning. Most Tennessee counties participate in NFIP.

  • Building permits. Tennessee requires residential building permits statewide for property tax assessment purposes. However, some counties have opted out of enforcing building codes, meaning you need a permit but no one inspects your construction for code compliance. This distinction matters: a permit is not the same as code enforcement.

The Benefits and Risks of Buying in an Unzoned County

Benefits

Unzoned counties attract buyers who want flexibility. Without zoning restrictions, you can generally build what you want, where you want, using the materials you choose. This appeals to homesteaders, hobby farmers, people building alternative or owner-built homes, and anyone who wants to avoid the permitting complexity of zoned jurisdictions.

Property in unzoned rural counties also tends to be significantly less expensive than comparable acreage in zoned, developed areas. Combined with Tennessee's lack of a state income tax and the possibility of low property taxes through the Greenbelt program, rural Tennessee land can be very affordable to own.

Tennessee's Greenbelt program (formally the Agricultural, Forest and Open Space Land Act of 1976) allows qualifying land to be taxed based on its present agricultural or forestry use rather than market value. To qualify, you generally need at least 15 acres engaged in agricultural activity producing a minimum average annual gross farm income of $1,500 over any three consecutive years. The tax savings can be substantial, but be aware that if you change the land's use, you will owe rollback taxes for the previous three years.

Risks

The same lack of regulation that gives you freedom also applies to your neighbors. Without zoning, there is no county mechanism to prevent incompatible land uses from appearing next door. A chicken farm, a gravel pit, or a commercial operation could set up on an adjacent parcel, and you would have limited legal recourse through the county.

Other risks include:

  • No guaranteed infrastructure. Unzoned rural areas typically lack municipal water, sewer, and sometimes even maintained roads. You will likely need a well and septic system, and you should verify road access and maintenance responsibilities before buying.
  • Resale considerations. Some buyers are uncomfortable purchasing in areas without zoning protections, which can affect your pool of future buyers.
  • Changing regulations. Counties can adopt zoning at any time. If your area begins to develop, the county may eventually implement zoning that restricts your current or planned use. Conversely, Tennessee's legislature has been active on property rights. Recent bills like SB2582 (2025) have proposed prohibiting zoning regulations that diminish property values.

How to Do Your Due Diligence in an Unzoned County

Whether a county has zoning or not, thorough due diligence matters before buying Tennessee land. Here is a practical checklist:

  1. Contact the county planning commission. Even without zoning, ask about subdivision regulations, any pending zoning proposals, and whether the county participates in NFIP floodplain management.

  2. Search for deed restrictions. Review the property deed, plat maps, and any recorded covenants at the county register of deeds office. Private restrictions can be more limiting than zoning.

  3. Check septic feasibility. Contact TDEC or a licensed soil scientist to determine whether the land can support a septic system. A failed perc test in an area without sewer access can make the property unbuildable for residential use.

  4. Verify road access. Confirm whether the road serving the property is publicly maintained or private. If private, understand the maintenance agreement and any easement rights.

  5. Assess utilities. Determine the availability and cost of electricity, water (well or municipal), and internet service. Rural properties may require significant investment to bring utilities to the building site.

  6. Consult a local attorney. A Tennessee real estate attorney familiar with the county can identify issues that online research may miss, including pending development plans, water rights, and easement disputes.

How LandWise reports zoning in unzoned counties

For a county like Hamilton or Knox that publishes zoning GIS, LandWise queries the county endpoints and returns the per-zone coverage percentage, the primary zone code and description, and a mixed-zoning flag if your parcel straddles districts. For a county like Bledsoe with no county-wide zoning, LandWise returns the county's zoningNote text verbatim instead of a fabricated zone designation; you see the same caveat the county itself would give you. That distinction matters: a missing zoning section in your report doesn't mean LandWise failed to fetch data, it means there is no zoning to fetch, and the rest of the parcel's risk picture (flood, wetlands, soils, road access, utilities) does the work of constraining what you can build there. For related context, see Tennessee easements and Tennessee property taxes for vacant land.

What we'd actually do first

Call the county planning commission before you walk the parcel. Two five-minute questions answer most of the unzoned-county uncertainty: does the county have subdivision regulations (almost all do, even without zoning), and is there a current effort to adopt zoning. The first tells you whether you can actually split the tract later; the second tells you whether the freedoms that attracted you to an unzoned county might disappear in a year.

Then pull the deed and any recorded covenants from the county Register of Deeds. Private restrictions are often stricter than the zoning that doesn't exist, and they're the single most common source of "I didn't know I couldn't do that" complaints from buyers in unzoned Tennessee counties.
